the Ovula o/Loranthus and Viscimi. 85 



e. Brownish rather indistinct line running- towards the excavation, in 

 which the now imperfect nucleus, f, of a cordate shape, is deve- 

 loped. The same phœnomena occur as in Loranthu.s Scumtld. 



Fig. 11. Longitudinal section of a more advanced fruit; the figures have the 

 same references. The mucilaginous or now viscous tissue, b, is 

 •much enlarged, and is deposited in cavities, which appear to be tole- 

 rably distinct from each other ; the two basilar ones, as in some 

 others, are the largest, d. The diminished remains of the basilar 

 part of the originally dense ovarium ; it is the persistence of this 

 portion that causes in part the production of the horns of the albu- 

 men. The line e is very distinct, and the tissue forming the mar- 

 gins of the now large cavity much sphacelated. 



f. The albumen considerably altered in shape, g. The young em- 

 bryo attached very slightly to the part of the albumen correspond- 

 ing to the termination of the line e.

Fig. 1. Longitudinal section of an ovarium of a Loninthus, species unknown, 

 a short time after the fall of the flower, u. Outer tissue of parietes 

 of the caljTc. b. Inner ditto commencing to become viscous, c Ova- 

 rium, d. Its base and denser portion, which produces the same 

 effect on the albumen as above noticed, e. The line descending from 

 the apex of the remains of the conical base of the style, f. Ovulum. 



Fig. 2. Section not truly central. «,&. Refer as before, c. The fibrous walls 

 of the ovarium, d. Its stalk, which is surrounded by viscous tissue. 

 The sphacelated apex of the remaining base of the style is evident. 

 The communicating sphacelated line e has disappeared, the tissue 

 continuous with the base of the style being truncate, e. The broad 

 cellular attaching process of the albumen, f. The albumen : rudi- 

 ments of two of its ascending cornua are visible, g. Tlie embryo 

 hanging down into a cavity formed in the albumen by excavation. 



Fig. 3. Embryo detached. Its funiculus is long, loosely cellular, and evascular,
